IMPROVEMENT IN TUBULAR LANTERNS.

Specification describing certain Improvements in Tubular Lanterns, invented by JO- sEPH S. DENNIS, of Chicago, in the county of Cook and State of Illinois.

This invention relates to an improvementin the construction of that class of lanterns well known to the art as tubular lanterns, and the invention consists especially in the construction and arrangement of the bell 01 receiver placed above the flame in connection with the side tubes; the said receiver or bell being extended laterally in the present invention, and attached by proper means to the said sider tubes, thus adding greatly to the strength and durability of the lantern.

In the accompanying drawing, Figure l represents a front elevation of a tubular lantern embodying my improvement, and Fig. 2, a horizontal section of Fig. l on the line x x, looking downward.

Like letters of reference made use of in the several figures indicate like parts.

General Description.

case, to the tube D, is attached the spring devicefor retaining the globein position by means of a downward pressure exerted from the tube or bell through the spring and upon the globe at its upper rim, and necessarily with some orce.

When the globeholding spring is to be released, more or less lateral pressure occurs, especially when the style shown in the drawing is used, tending to push the bell out from between the tubes E, straining and loosening the joints, and tending ultimately, by the torsion thus produced, to destroy the integrity of the joints at the juncture of the tube D with the tubes E, and tending to crimp and loosen the bell C from the tube D. To obviate this tendency, the metal straps a a are soldered or otherwise attached to the sides of the bell C, and extended out and connected to the tubes E E upon each side. By this simple device a perfect bracing of the entire upper portion of the lantern is effected, and the difficulty hitherto existing entirely done away with.

An equivalent to the employment of the separate straps or pieces a a would be the extension of the bell itself so as to reach the tubes and be joined thereto, and I contemplate so attaching the bell, either .by enlarging the entire diameter thereof, or by making it of a greater diameter in one direction than another.

(Naim.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The combination of the bell C and tubes E E of atubular lantern, when the bell is attached laterally to the tubes, in the manner substantially as specified and shown.
